Answer:
Explanation:
molecular weight of N₂H₄ is as follows
2 x 14 + 4 x 1 = 32
so 32 gram of N₂H₄ is equal to one mole of N₂H₄
25 gram of N₂H₄ will be equal to 25 / 32 mole of N₂H₄
so numerical quantity needed to convert grams of N₂H₄ to mole is
1 / 32 or .03125 . This number needs to be multiplied with grams of N₂H₄
to convert it to number of moles.
